Gross Calorific Value
Calorific value is the heat energy released per unit mass of fuel burned as shown by Formula F7.1. Gross calorific value, or higher heating value (HHV), is the total heat released making no allowance for the latent heat required to vaporize the liquid water produced by the combustion process.Hence it is a theoretical parameter and is rarely used. The net …

estimates GCV based on moisture and ash data, was provided by Mazumdar (1954) (Eq.1): GCV= 85.6{100-(1.1 A + M)} – 60 M (1) Where A is ash yield; and, M is moisture content. Both A and M are measured at 60% relative humidity and 40 °C. This GCV prediction formula has been widely applied by some end user industries in India (Dey et al., 2012).
